Explanation:
To find the sale price of the coat that is marked "1/3 off" from its regular price of $150, follow these steps:
1. Calculate the discount amount:
- 1/3 off means a discount of 1/3 * $150 = $50.
2. Subtract the discount amount from the regular price:
- $150 - $50 = $100.
Therefore, the sale price of the coat is $100.
